Hi everyone,

I'm sorry to announce that I'm no longer maintaining the chips_choice package. It's been a great project, but it's become too difficult to maintain.

In its place, I've released a new package called choice. The combination to smart_select and chips_choice with cleaner, more flexible, and composable API for creating inline or prompted choice widgets with single or multiple selection.

I hope you'll check out choice. I think you'll find it to be a great replacement for chips_choice.

Thanks for your understanding.
